Driving With No Thermostat

[bdj5773]

If you start car and have the AC turned off, let the car idle for a minute, open hood and listen and/or look at cooling fan. Either have someone or yourself turn on the AC. You should hear and/or see the cooling fan increase in speed. You can also use OBD11 tester if you have one like I mentioned before. This will indicate if actuator, pump and fan are working. The actuator is the easiest and cheapest part to change if thats whats wrong. You can get one at wreckers for $10.00 or new for $140. I got one from wreckers because they do give 90 day warranty where I live , not sure where you are.

Gave the AC test a try and sure enough the fan sped up. I have installed a new TS and bled out the coolant system. I will just have to drive around and see if the overheating issue is still there. Is it possible that even though the fan sped up that it still isn't spinning as fast as it should?

of course it is, was the change in speed small or large?

The fan definitely sped up a good bit but that still may not be what it is supposed to be. Still haven't had a chance to get it out and see what it does. Snowy and cold weather have kept me in. Probably would be better to hook up a diagnostic tool to know for sure.
